There seems to be some disagreement when it comes to grading coins when it comes to the true (technical) grade of a coin and the market grading employed by TPGs. It seems that the more seasoned collectors will give a grade based on strike, wear and contact marks. This method can be used on every coin that was die struck. On the other hand Market grading is somewhat forgiving of certain criteria that would otherwise lower the value of a coin. This grading changes with different series of coins, particularly when it comes to higher value coins.
For years, I trusted the grades of TPGs. After all, if I wasn't in love with the coin, the grade would stand and the coin would be easily marketable. These days, I almost prefer to buy raw coins and trust my own grade because the grade on the slab has become less and less accepted. Early on with PCGS and NGC, the grading was strict and you could argue too strict. Today, it seems like the opposite, I see MS-66s that would have had a hard time getting a MS-64 twenty years ago. Why have the standards changed? Wouldn't it be nice if all slabbed coins looked as nice as their old rattler counterparts. I thought the idea of sight unseen marketability was the goal of TPGs. If not, what is point of them at all. Maybe, I'm just old school.
